Your Shopify store has problems.
I fix them permanently.

Custom Shopify development, B2B wholesale infrastructure, and deep technical problem-solving for brands doing $1M+ in revenue. I find the root cause, not the band-aid.

Sound familiar?
Your apps are fighting each other and nobody can figure out why your site is slow
You're paying $2,000+/mo for Shopify Plus just for basic B2B features
Your mobile conversion rate tanked and you don't know when or why
The last developer "fixed" something and now three other things are broken
Your theme migration went sideways and you lost customizations you spent months building
Google is penalizing your store for schema conflicts you didn't even know existed

Technical challenges that keep merchants up at night

These aren't hypotheticals. These are real problems I've diagnosed and resolved for real brands with real revenue on the line.

🔍

App Conflict Resolution

Your apps installed fine individually. Together, they're a disaster.

Third-party apps inject scripts that conflict with your theme, with each other, and with your customers' browsers. I trace the exact collision points through console analysis, network profiling, and code audits, then implement fixes that let everything coexist.

B2B Wholesale Infrastructure

Shopify Plus costs $2,000+/mo. You don't need it.

Gated storefronts, customer-specific pricing, net-30/60/90 payment terms, TOS consent, freight estimation, and automated due-date calculations. I build Plus-level B2B functionality on standard Shopify plans using custom webhooks and API integrations.

Payment Terms Site Gating AWS Lambda Webhooks

Performance & Mobile Optimization

Every second of load time costs you 7% in conversions.

I audit your full script stack, identify render-blocking resources, reduce bundle sizes, implement conditional loading, and fix the iOS Safari crashes that tank your mobile revenue. Real performance work, not just compressing images.

Security & Checkout Protection

There might be an exploit in your checkout flow right now.

Loyalty programs, gift tools, and discount apps can create loopholes that let customers bypass qualification logic and check out with items they shouldn't have. I identify these vulnerabilities and patch them before they cost you.

Theme Migration & Upgrades

Updating your theme shouldn't mean losing 6 months of work.

Full theme migrations with complete feature parity. I document every customization, rebuild them on the new version, QA across devices, and maintain rollback procedures at every step. Nothing gets left behind.

Analytics & Tracking Architecture

Your conversion data is wrong, and you're making decisions based on it.

Google Tag Manager implementation, Enhanced Conversions for Google Ads, Klaviyo/Meta pixel integration, and custom data layer architecture. Clean, accurate attribution so you know which dollar actually drove the sale.

The person behind the code

I'm Baruch Havia, founder of BH Consulting. Based in South Florida, I work with established e-commerce brands that have outgrown basic Shopify setups and need someone who can handle real technical complexity.

My path into development wasn't traditional. I came through quality assurance, which means I think about edge cases, failure modes, and regression testing before most developers even start writing code. That background is why my clients don't get surprises in production.

I work with advanced AI-augmented development workflows that let me deliver at a speed and depth that most solo consultants can't match. I use AI as a force multiplier for research, code review, testing, and documentation, while maintaining the judgment and accountability that only comes from a human who understands your business.

No account managers. No handoffs. No month-long discovery phases. When you hire me, you get me, and I ship in days, not weeks.
